Maserati instrument can't start when it vibrates.

Poor line contact. Maserati's instrument is shaking and can't be started, which is due to poor line contact. Maserati dashboard has poor contact with the control circuit, or the control dashboard circuit board is faulty. If the idle speed is unstable during the crash, the pointer on the dashboard jumps, and the accelerator reacts slowly when stepping on the accelerator, it is that the accelerator and air intake are dirty.
